Chrysanthemum named &#39;Zanmufive&#39;

ABSTRACT

A  chrysanthemum  plant named ‘Zanmufive’ characterized by its medium sized blooms with red ray florets and prolific branching; natural season flower date September 4-8; blooming for a period of 5 weeks.

BACKGROUND OF THE INVENTION

‘Zanmufive’ is a product of a breeding and selection program for outdoorpot mums (garden mums) which had the objective of creating newchrysanthemum cultivars with a decorative type flower, a natural seasonflower date around September 4-8; blooming for a period of 5 weeks. Thenew plant of the present invention comprises a new and distinct cultivarof chrysanthemum plant ‘Zanmufive’ is a seedling resulting from acrossing program, set up by a previous breeder, and which records areunknown to the inventor. The new and distinct cultivar was discoveredand selected as a flowering plant by Wilhelmus Bernardus Blom on acultivated field in Rijsenhout, The Netherlands in 2005. The first actof asexual production of ‘Zanmufive’ was accomplished when vegetativecuttings were taken from the initial selection in 2005 and propagatedfurther in a controlled environment in Rijsenhout, The Netherlands. Thenew cultivar has been found to retain its distinctive characteristicsthrough successive propagations.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The present invention of a new and distinct variety of chrysanthemum isshown in the accompanying drawings, the color being as nearly true aspossible with color photographs of this type. Pictures were taken of 16week old plants.

FIG. 1 shows a plant of the cultivar in full bloom

FIG. 2 shows the various stages of bloom of the new cultivar.

FIG. 3 shows the various stages of foliage of the new cultivar.

DESCRIPTION OF THE INVENTION

This new variety of chrysanthemum is of the botanical classificationChrysanthemum morifolium L. The observations and measurements weregathered from plants grown out door in Rijsenhout, The Netherlands undernatural day length and temperature and planted in week 24 in 2006. Thenatural blooming date of this crop was September 4-8 (week 36). Theaverage height of the plants was 28 cm. No growth retardants were used.No tests were done on disease or insect resistance or susceptibility. Notests were done on cold or drought tolerance. This new variety producesmedium sized blooms with red ray florets blooming for a period of 5weeks.

From the cultivars known to inventor the most similar existing cultivarin comparison to ‘Zanmufive’ are ‘Plutores’ (U.S. Plant Pat. No. 12,919)and ‘Manakin’ (U.S. Plant Pat. No. 11,521) When ‘Plutores’, ‘Manakin’and ‘Zanmufive’ are being compared the following differences arenoticed: The differences of ‘Plutores’, ‘Manakin’ and ‘Zanmufive’ are(1) Flower type, (2) Flower size and (3) Natural season flowering time(1) The flower type of ‘Manakin’ is single, while that of ‘Plutores’ and“Zanmufive” is double (2) The flowers of ‘Manakin’ and “Zanmufive” aresmaller than those of ‘Plutores’ (3) The plants of ‘Plutores’,“Zanmufive” and ‘Manakin’ flower at different times, resp. in lateAugust, early and mid-September.

The following is a description of the plant and characteristics thatdistinguish ‘Zanmufive’ as a new and distinct variety.

The color designations are taken from the plant itself. Accordingly, anydiscrepancies between the color designations and the colors depicted inthe photographs are due to photographic tolerances.
